CHURN-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 427,457, dated May 6,1890.

Application filed February 6, 1890. Serial No. 339,392. (No model.)

T0 all whom it may concern.-

Be it known that I, HARVEY BROKAW, a citizen of the United States ofAmerica, residing at \Vapakon eta, in the county of Auglaize and Stateof Ohio, have invented certain new and useful Improvements inChurn-Closures; and I do herebydeelare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

My invention relates to closures for churns; and it consists in theimproved construction hereinafter described and set forth, whereby asimple an d efficient closure is provided that may readily andconveniently be locked and unlocked, the several metal parts being sodisposed that they are of simple form and can be severally produced inthe form of inexpensive castings.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective view of a churn-closure and its devices in a lockedposition and constructed in accordance with my improvements, and Fig. 2is a vertical sectional View.

Internally and near the edge of the bodyA is a metal ring B, upon theupper side of which vertical lugs 04 are cast, said lugs having ahorizontally-extending head I), the adjacent faces of therunder side andadjacent edge of the lug being plane-faced to forman abrupt portion.ring B is turned to form a shoulder c, as shown in Fig. 2.

A circular disk C, of wood, has attached thereto an annular ring D, thehorizontal portion of which is provided with ears (Z, through whichscrews pass to attach it to the wooden disk, an annular gasket 6, ofcork, being clamped between the disk and ring, so that its under channelwill receive the shoulder a to present an air-tight bearing thereat. On

the upper side of the ring at equidistant points are projections cl,each of which has a radial channel increasing in depth toward theoutside. A vertical loop 6 spans the channel of each projection.

The inner edge of the metal An arched bar or casting E has its lowerends bent horizontally and perforated for the passage of screws tosecure said bar centrally to the wooden disk, and the central part ofsaid bar is enlarged and perforated to form a bearing f, the perforationin which is internally threaded for the passage of a screwthreadedspindle F, the upper end of which carries a handle g, while the lowerend is connected to but turns in the casting G, having four lateral earsh, each of which is bifurcated and carries a pin 1', with which engagesthe inner hooked end j of one of a series of four radial arms, the innerend of each arm adjacent to its hookbeing provided with a shoulder 7t,located adjacent to the outer ends of the ears to brace the connectionsrelative to each other and prevent unnecessary vibration of the parts,and also enable the ears to bear directly upon and operate the arms whensaid casting has arrived at its lowest point of descent. The outerportions of the arms are seated in the channels of the projections ofthe ring and play through the loops of the same.

In practice the closure with its parts is placed in position on the ringA so that the inner shoulder of the latter will enter and bear in therecess of the gasket. The casting G is meanwhile at its highest point ofmovement, and hence the arms are so inclined that their outer ends areat their lower point. The closure can be rotated to a limited extent tobring the outer ends of the arms in contact with the lug a beneath theheads of the same. The threaded spindle can then be revolved, so as toeffect the descent of the casting G, which in turn depresses the innerends of the arms, and, inasmuch as the upper ends of the channels in theprojections d serve as fulcrums for said arms, the outer ends of saidarms will be elevated, so as to bind against the under faces of theheads of said projections. The slight movement of the spindle in areverse direction will release the parts sufficiently to admit of thereverse movement of the closure and the disengagement of its arms. Itwill therefore be seen that the several parts constituting myimprovement are but few and simple and that they may be readily producedin the form of castings. 3y ein i loying the central frame G I not onlyavoid a multiplicity of connections and parts to secure the same end,but reduce the number of sections heretofore necessary to secure similarresults and positively etfect the movement of the arms.

I am aware that prior to my invention it has been proposed in aconstruction somewhat similar to have a vertical threaded spindleattached to the top of the disk and a nut and casting playing upon thesame, the casting havin arms pivotally connected thereto at their innerends. I am also aware of a proposed prior construction wherein the diskcarries a threaded socket at its upper side, in which a threaded spindleplays vertically, a castin being supported on said spindle and adaptedto be locked and depressed by a camlcver. My invention will beprincipally distinguished from such constructions in that the screwtravels in the arched bar and permanently carries a casting G at itslower end, the arrangement bein such that the said cast-in G and itsarms are positively operated, and the arched bar will relieve the topand. other parts from considerable of the strain.

I claim- 1. The combination, in a closure for churns, of the bodyhavinhooked lugs a, a disk provided with an arched bar, a threaded spindleseated therein and carrying a frame at its lower end, and arms pivotallyconnected to said frame, fulcrumed on the disk, as de scribed, andadapted to have their outer ends elevated to engage the lugs when theframe is depressed, substantially as set forth.

2. The combination, in a closure for churns, of the body having hookedlugs (I, a circular disk having projections (1, provided withoutwardly-inclined channels, an arched bar secured on said disk, athreaded spindle hearing therein and carrying a frame at its lower end,and arms pivotally secured to said frame, fulcrumcd on the disk, asdescribed, and bearing in said channels, and adapted to have their outerends elevated to engage the lugs when said frame is depressed,substantially as set forth.

3. The con'ibination, in a ehurn-body and closure therefor, of aringA,internally seated in the body, as described, and ljiaving hookedlugs a, a disk provided with an arched bar, a threaded spindle bearingtherein and carrying a frame at its lower end, and arms pivotallyconnected to said frame and engaging fulcrums on the covendisk, andadapted to have their outer ends elevated to engage the lugs when theframe is depressed, substantially as set forth.

4. The combination, in a churn-body and closure therefor, of the hookedlugs a, a disk having an annular ring provided with projections (1,having channels inclining outwardly, and loops spanning the same,ail-arched bar seated on the said disk, having a threaded spindlecarrying a frame at its lower end,and arms pivotally connected to saidframe and bearing in said channels to engage said lugs, and adapted tohave t-heirouter ends elevated to lock the parts when the frame isdepressed, substantially as set forth.

5. The combination, in a-churn-body and closure therefor, of the hookedlugs (1,, a circular disk having an annular ring of larger dimensionsecured marginally thereto to confine a gasket, and having projectionson its upper side provided with channels inclining outward, and anarched barseated on the said disk, having a spindle carrying a frame atits lower end, and arms pivotally connected to the frame and bearing insaid channels to engage said lugs, substantially as set forth.

' (3. The combination, in a churn-body and closure therefor, of thehooked lugs (0,, carried by thebody,acovendisk havingchanneledprojections d adjacent to its margin, an arched bar seated centrally onsaid disk, a threaded spindle bearing in said bar and frame carried bysaid spindle, and the arms pivotally connected to the frame andshouldered adjacent thereto and bearing in said channels to engage saidlugs a, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
